'Pray for' in the Bible

We give thanks always to God the Father of our Lord Jesus Christ [when we] pray for you,

For this cause we also, since the day we heard it, do not cease to pray for you, and to desire that ye might be filled with the knowledge of his will in all wisdom and spiritual understanding;

[We pray for you] to live a life deserving of the Lord, pleasing to Him in every way, producing fruit in every good deed and growing in the knowledge of God.

At the same time pray for us, too, that God will open a door [of opportunity] to us for the word, to proclaim the mystery of Christ, for which I have been imprisoned;

This greeting [is being written] by me, Paul, in my own handwriting. Remember my imprisonment. [Note: This was probably a request for them to pray for him]. May God's favor be with you.
